Specification of Letters Patent Patented Nov. 2%, 191?.

Application filed April 2, 1917. Serial No. 159,100.

To all whom it may concern:

Be it known that I, GEORGE A. WILSON, a citizen of the United States, and a resident of Chase Mills, in the county of St. Lawrence and State of New York, have invented certain new and useful Improvements in Sediment-Testers, of which the following is a specification.

My presentvinvention relates generally to testing apparatus, and more particularly to apparatus for testing the sediment of milk, my object being in the first instance to provide a sanitary apparatus of this character fully answering the standard health laws governing the production of devices of this nature, and one which will be effective and eflicient in use.

A. further and more specific object of my present improvement is theprovision of a testing apparatus, the parts of which may be readily disassociated from one another in order that all surfaces in contact with which the milk comes in the operation of the apparatus may be readily reached for cleansing purposes.

A further object is to provide removable cup supporting means in the form of holders, for the support also of the sediment pads, the construction of which permits of readily locking and releasing the same in placing and removing such pads.

Other objects residing for the most part in the details of construction of the various portions of my improved tester, will be'apparent from the following description thereof, reference being made to the accon1- panying drawings, forming a part of this specification and wherein- Figure 1 is atop plan view,

Fig. 2 is a side view partly in elevation and partly broken away and in sections.

Fig. 3 is a vertical transverse section takendsubstantially on the line 3-3 of Fig. 2, an

Fig. 4c is a detail perspective view of one of liile cups and its holder removed from the tan Referring now to these figures and particularly Figs. 1, 2 and 3, my invention contemplates the provision of a tank, generally of an elongated, rectangular form, having an upper closed chamber 10 extendin for the full length thereof and divided y a horizontal partition 11 from the lower enlarged portion 12 of the saidtank, the latter of which is open at its base and provided supports or legs 16 with a depending surrounding flange 13 arranged to telescopically fit within the upstanding fiange 14 of the tank base 15, the latter of which may have depending end tomaintain the same in upright position upon a flat supporting surface, and is provided with a depending central outlet 17 to extend within the mouth of a can or other milk receptacle, and with a depending annular flange 18 surrounding the outlet 17 in spaced relation to lap the outer portion of the pan or other receptacle into which the outlet 17 is extended.

The top wall 19 of the casing closes the upper portion of the upper chamber 10 and is provided with a longitudinal series of depending tubes 20, the lower ends of which extend through the horizontal partition 11 and open into the lower enlarged portion 12 of the tank, the said upper closed chamber 10 having end nipples and the like 21 to receive the inlet and outlet pipe (not shown) by which steam, hot water or other heating fluid is respectively conducted to and away from the closed chamber 10, to circulate in the latter around the several tubes 20 and maintain a substantially uniform temperature in the pipes so as to obviate deleterious efiects in operation due to abruptly changing temperature and the extremes of heat and cold, it being obvious that a cooling fluid may be substituted for a heating fluid where it is desired to reduce instead of increase the temperature within the tank.

The upper open ends of the tubes 20 receive the holders for a plurality of milk receiving cups 22, the upper ends of the latter of which are open and the lower reduced and open neck portions 23 of which are removably supported by the holders as presently described. it

Each of the holders referred to consists of upper and lower annular plates 24: and 25 as best seen in Fig. 4, the former having projecting tubular exrib 39 of the lower plate 25,

lips" 30, zone of which is provided with spaced upstanding ears 3:1 engaged by a pivot pin "32 extending through one of the bearingsQE) and forming a hinge at oneside :of the holder. upon which the upper plate ;is movable vertically with respect to the lower plate when in position .uponwthe tank, for a purpose-to be presently described-,the 0p- .posite bearingl 29 of the upper plate receiving afpin at t e upperendof a .pairof links :83 supporting in spaced pivotal relation an eccentric clamping member 34 movable abeneath and in engagement. with the lip 30 of :the :lower ,plate25 with the parts in opera- 7 'tive position as shown in Fig. 3.so as ;to clamp the two plates of the holder firmly in connection with one another.

Adjacent its upper end thevdependingtubularextensionQ'? of the lower plate-25 of each of the holders, supports a reticulated diaphragm or disk 35, suitably connected thereto or a part thereof, and which may be either of wire mesh .or perforate metal, the disk or diaphragm just described being -located immediately beneath a counterbore 36 :at :the upper endof the said tubulaiwexten- -sion, 1 adapted for the reception of the sediment holding .pad i 37. The lower surface of the :upper plate-24c of theholdenhas an annular rib 37 depending around the lower vend of the tubular extension 26,1to enter the :counterbore=36,:as seen in FigsQ and3,ancl :to ,seat upon and "firmly hold the sediment .pad s37 :inplace, the-lower surface oftheupper plate 241 also having an annular-channel in which a .gasket 38 is seated, which is firmly pressed up on an upstanding annular when the clamp 3 so as to effec- 34 isengaged as seen in Fig.

' 'Oneendpf the tank 10, as seen in Figs. 1 and 2, ispreferably provided with a vertical cylindrical holder A0 for a series of the pads 37 so that such pads may be conveniently reached for use, the receptacle a0 having a removable coven tll silt is. obvious, furthermore, that-the'tank may be removed from its base 15,..so that upon removal of llBsSBVQI'SJl :holders with 7 their cups '22 ,from the tank, the latter ,may
